[FFmpeg-user] Sony XAVC 422 10-bit 4K

Hi Guys,

Please find below the log I get when I convert XAVC 422 10-bit 4K material into ProRes with the latest trunk.

I am worried about the 5 MXF parsing lines:

[mxf @ 0x2bbcf20] could not resolve sub descriptor strong ref
[mxf @ 0x2bbcf20] source track 11: stream 9, no descriptor found
[mxf @ 0x2bbcf20] Stream #9: not enough frames to estimate rate; consider increasing probesize
[mxf @ 0x2bbcf20] decoding for stream 0 failed

And the post-processing line: "Clip0042.MXF: Operation not permitted".

The output file looks fine. But I would like to know what those error messages mean and eventually, to get rid of them.

Regards,

Vincent
